Two buildings have been evacuated this morning as police and fire crews investigate a bomb threat to a University of California at Berkeley-affiliated office in Emeryville.

The bomb threat to office space rented by Lawrence Berkeley National Laboratory in the EmeryStation East building at 5885 Hollis St. was reported around 7 a.m., UC Berkeley police Lt. Eric Tejada said.

As of 9:45 a.m., a second office building located across the street from EmeryStation East in the 5800 block of Hollis Street had also been evacuated as a precaution.

The two floors that house the lab facility had not opened for the day when the threat was received and are remaining closed during the investigation. Occupants of other parts of the building also chose to leave as a precaution, Tejada said.

Bomb-sniffing K-9s from the UC Berkeley Police Department, the Alameda County Sheriff's Office, the U.S. Coast Guard and the U.S. Department of Homeland Security were also there to inspect the building.
